PhysicsLogic / Bell 1964 and CHSH 1969

Local Responses and Averaged No-Signalling

Read deterministic locality as remote-setting independence, then distinguish it from an observed marginal law.

Definitions and assumptions

Scope and physical limitations

The framework equivalences concern a specified deterministic response model at fixed hidden state, not a probability law after averaging. They expose literal equality of response values and require no new physical definitions. The finite diagnostic uses one common fair hidden bit for all settings. Both observed marginals are uniform despite a remote-setting-dependent response at each hidden value. Its complete joint law also has a distinct local realization. Thus the example does not violate a Bell inequality or exclude a local model of the observed statistics; it prevents inference of locality of a particular hidden-state realization from those statistics. Empty domains remain possible for the universal framework laws; this Boolean diagnostic has two settings, two positive-probability hidden values and two outcome channels.
